The new G Series is compliant to XQD Format Version 2, both PCI Express Gen.2 and USB3.0 interface are supported on a newly-developed controller for high performance.
The G Series delivers increased read 400MB/s*1 and write 350MB/s*1 speeds, which is three times the speed of the previous N Series cards.

The G Series is supplied with a dedicated USB 3.0 adapter, which offers convenience and efficiency for professional workflows. It dramatically reduce ingest time by less than half compared to the fastest Compact Flash card*2 even for large quantities of RAW images or data-intensive 4K video files.

This tool supports applying a driver update program released by Microsoft, which increases the maximum USB transfer size in Windows 7, by setting registry required by this update.
After setting registry with this tool, the maximum USB transfer size for reading the G Series XQD memory cards will be increased (to 1 MB.)
